Abstract:To explore the preparation of civilian electromagnetic shielding and military stealth carbonbased highperformance waveabsorbing materials,the different compounding and preparation methods of carbonbased waveabsorbing materials such as carbon nanotubes and magnetic metal composites,carbon nanotubes and ferrite composites,carbon nanotubes/polymer composites,carbon,and graphitebased composites were studied.The different characteristics, influencing factors, performance characteristics and related applications are compared.It is indicated that multivariate compounding,low dimensionality and process optimization are effective ways for the preparation of highperformance carbonbased microwave absorption materials.
